“I’m 25 years old and have been an entrepreneur since the age of 19. I found success with that early on and ended up dropping out of college. I made good money, but wasn’t happy.” At that point, the TikTok creator took a risk and decided to “stop all that and start something more fun that I’m interested in and that’s how Knowledgesaurus started. I started this account 1/1/2021 with the goal of growing it and making it my full-time job and within 110 days, I was able to reach 1 million followers, which I’m so thankful for!”

When asked how he came up with the idea for the "How Rare Are You?" series, Knowledgesaurus said it started after making a bunch of videos and seeing what people enjoyed watching. “I realized that people love to know information about themselves and love statistics. So that’s how the series began.”

“I always loved knowing random useless information to surprise people with,” the content creator said and added: “I think it all started when I was younger. If someone was talking about something I didn’t know much about, I would go and look up stuff about it and find interesting information about that topic so I could have a better conversation next time.”
